Perform a Scenario Design analysis as described below. Consider whether it makes sense for your selected recommender system to perform scenario design twice, once for the organization (e.g. Amazon.com) and once for the organization’s customers. Attempt to reverse engineer what you can about the site, from the site interface and any available information that you can find on the Internet or elsewhere. Include specific recommendations about how to improve the site’s recommendation capabilities going forward.
Slickdeals is an internet deals monitoring site. It hosts a combination of deals that are both user found and sponsored. It has a basic reccomendation system so show deals that are active that may be applicable to the user.
I personally use Slickdeals a lot for monitoring power tool deals.
Slickdeals, the recommender system
I think there are two main areas for improvement for Slickdeals, the first would be to integrate in bots to monitor pricing sites like camelcamelcamel, and use chagnes in price to indicate changes in deals.
Secondly, I believe that a bot could be implemented to test user’s deals to indicate if they are still valid or not, as a way to better provide feedback on the website!
I’d highly advise you check it out if you are shopping for just about anything!
